Menendez, who posted a statement via his wife's account on X, says that Ryan Murphy's downplaying of male rape victims' experiences is harmful, writes Variety.
"It's sad to know that Netflix's dishonest portrayal of the tragedies surrounding our crime has made us take several steps back in time. To a time when the prosecution built their narrative on the assumption that men cannot be sexually exploited and that men experience rape trauma differently from women", he writes.
He calls the portrayal of him and especially his brother Lyle "defamatory slander".
Erik Menendez confessed to the murder to his psychologist in 1990 and both brothers have admitted to murdering their parents after a childhood filled with sexual abuse by their father, while their mother knew but never intervened.
In "Monsters: The Lyle and Erik Menendez story", viewers follow the brothers, played by Cooper Koch and Nicholas Alexander Chavez, after the murders. The parents are played by Javier Bardem and Chloë Sevigny.
Ryan Murphy's Netflix drama is the second season of the series "Monsters". The first season dealt with serial killer Jeffrey Dahmer, and when it was broadcast, several of Dahmer's victims' relatives criticized Murphy's dramatization of the murders, which they claimed re-traumatized them.
